Skywatcher 150/1200 f8 planetary Newtonian.
Bought this originally intending to set up a planetary rig but circumstances call for sale.
Will come with eyepieces and a collimation eyepiece. Not used by myself and has seen very little use. Mirrors in good condition

Hi All I’m considering purchasing an 8”aperture, f3.8 newtonian ( primarily for EAA) from Orion UK and would appreciate any input or feedback from anyone familiar with the product, the company or the purchasing process - and how to assess the compatibility with my current cameras.
This is would be a step up from my current equipment and entails selecting components that I’ve never used and know little about such as a rack and pinion focuser and components (ACU-3L), and coma corrector (Wynne Corrector). I’ve added links to these items below. I’m also feeling unsure of how to mate up my Zwo 178 and 294 cameras to the 3” focuser and whether there will be an acceptable match between the scope optics and my sensors.
I’m sure the folks at Orion UK will assist with all this but I’d sure welcome input from the Stargazer's Lounge community before starting the dialog with Orion UK.
thank you in advance for any help you can provide!

With reluctance I am looking to sell my 200mm aperture f5 Helios Newtonian OTA. (Helios is a brand that became incorporated into Skywatcher - this closely resembles Skywatcher OTAs)
The Helios is offered with single speed rack & pinion focuser, tube rings, 22 to 1.25" adaptor, dovetail bar and grab handle for £90 o.n.o. In good condition except that the dovetail bar appears to be discoloured by exposure to sunlight.
I have not used the telescope for many months and with a persistent problem in my right arm my enthusiasm for moving heavy kit around has diminished.
Buyer to collect from North Bucks.
Offered as option with the OTA: EQ5 mount with RA drive + 6 volt sealed lead-acid battery +charger + standard and extra long Dec slow motion manual shafts. £150. Condition - used but working.
If I sell the OTA I will be looking to dispose of its accessories:
9x50 Skywatcher straight finder - in excellent condition except that the small plastic dust cap is missing.
Cheshire collimator, boxed, as new.
Helical fine focuser, range 10mm, ID 1.25", screws into 2"adapter.
3x Datysun Barlow, as new, boxed.
Widefield eyepiece, 22mm f.l., 30mm body (note not 1.25") with built in focus, works well with this telescope.
Plastic collimation cap (no cost).
This bundle would cost around £114 new - offered if bought with scope at £75 o.n.o.
This is the first lights of my ASA 12"N f/3.62 (purchased in 2007) with my Moravian G4-16000 CCD camera using one KAF-16803 chip of 36mm x 36mm (4K x 4K).
The adjustments, collimation, ASA OK3-Z pression screws, asked a lot of attention.
For a precise collimation, i use the CATSEYE XL & XLKP kit.
This is the first 3hrs of exposures taken the last weekend in one night. The second night was too windy unfortunately.
